Is it possible that in such tall building the top floors can deviate from central vertical axis, for example in the strong wind when a huge force is put at the whole structure? Wonder if people on top floors will be able to ocasionally feel the building swinging left and right

I think they will feel the swinging a little bit. But in this type of huge buildings it's normal to install a dumper as a conterweight to minimize such vibrations. For example in Taipei 101:

FAQ: Why has construction slowed down recently?

Progress on the main core structure has slowed down recently because work is being done within the jump form rig apparatus to cast the first plant floors section. The plant floors have a greater floor-to-ceiling height than convention levels within the tower and as a result time is being taken to reconfigure the concrete casts within the jump form rig as required for these specific floors. I believe these floors have been cast already, however it will also take time to re-configure the jump form rig casts to begin casting the conventionally height levels again.

The plant floors here in the image below, are the first double storey additional heighted floors which are located above the podium structure:

Yes.
The Burj Khalifa had mechanical/plant floors in regular intermittent sections along the height of the tower, It is still obvious where the plant floors are as they are enveloped by a different kind of cladding than the other floors, I believe this will not be the case on the Kingdom Tower though.


https://ishitaunblogged.files.wordpr.../114.jpg?w=800

Wikipedia have done a nice summary of what a mechanical floor is, if you don't have a clue what I am talking about or why they are so necessary for such a tall building:
http://en.wikipedia.org/wiki/Mechanical_floor
Quote:
Burj Khalifa: Floors 17–18, 40–42, 73–75, 109–110, 136–138, 155, and 160–168 in the penthouse (total 25/168, 15%)

Saudi arabia is quite dependent on oil still indeed.

And Dubai was backed by its oil rich neighbour Abu dhabi in the financial crackdown.

I don't see the problem.

First of all, I don't think religion has anything to do with KT. And Islam is not inferior to Christianity or any other religion.
And if the Saudi's have dollar signs in their eyes, they are diferent from the - average- modern American , European, or Asian. So: also no issue.

Just be happy that KT is being built, and enjoy it's construction...!

Well, you allways see SOMETHING of the location of plant floors, like air intake grilles, etc.
And often the difference in floor height.
